Michael Keefe received his PhD in Mechanical Engineering, 1985, from the University of Minnesota, in the area of design. While completing his doctoral degree, he was employed by Honeywell, Inc., in Minnesota, as a development design engineer where his responsibilities included assisting in the design of weapon-system components through finite-element analysis and computational simulations of ballistic phenomena. Upon finishing his doctoral program he came to the University of Delaware to conduct research that applies computer-aided engineering and solid modeling while primarily teaching undergraduate design courses.

Dr. Keefe has been President of the University of Delaware Faculty Senate, is a Registered Professional Engineer in Delaware, was elected a Fellow of the American Society of Mechanical Engineers, and was also named 2005 Engineer of the Year by the Delaware Engineering Society. Dr. Keefe is currently interested in modeling the response of flexible, fabric-based, composite structures to ballistic loading. He continues to be an active member of the design faculty and the senior-design capstone program.
